Answer:
Since the two trains are heading in opposite directions, they are separating at 90km/hr+85km/hr=175 km hr. 700 km/175 km/hr= 4 hrs. The trains will be 700 km apart in 4 hours.

Answer:
3cm²
Step-by-step explanation:
Since the sizes are square tiles, to know the tile's side lengths that Dorian need to estimate, we will use the formula for calculating the area of q square
Area of a square = L²
L is the side length of the tiles
For the tiles with area 7cm²
7 = L²
L² = 7
L = √7
L = 2.65cm
For tiles with area 5cm²
5 = L²
L² = 5
L = √5
L = 2.24cm
For tiles with area 9cm²
9 = L²
L² = 9
L = √9
L = 3.0cm
Since for all the square tiles the length of the tile is ≤ 3 cm, then the tile's side lengths that Dorian will need to estimate is approximately 3cm
Answer:
X=10
Step-by-step explanation:
180-116=64
4x+7x+6+64=180
11x+70=180
11x=110
x=10
